Combined engine lubrication system: oil is supplied to the rubbing surfaces of parts under pressure and splashing

To check and remove the idle speed controller (IAC), you need to remove the throttle assembly completely (see "Removing the throttle assembly") or partially

Camshafts are replaced in the following cases:

All parts of the regulator must be clean before assembly, and the rubbing surfaces lubricated with engine oil

Before assembling the engine, it is necessary to clean all its parts from carbon deposits and resinous deposits

Oil pump - gear, with internal gears and pressure reducing valve

We remove the oil receiver when repairing the engine or when the oil receiver mesh is clogged, and the engine is starved of oil

We remove the throttle assembly for cleaning and when removing cylinder head assemblies

We remove the tips of the spark plugs together with the high-voltage wires, the ignition coils (you can only disconnect the connectors by leaving them on the valve cover), the throttle cable and, having disconnected the wires from the sensors of the lubrication and cooling systems, remove the wiring harness from the brackets of the head cover .

Removal and installation of the cylinder head can be found in the article - Replacing the cylinder head gasket of the VAZ-2126 engine
